JengDeal pick: B.AI invite QW4Z3F — credit-based multi-model LLM service
One account, many models? B.AI's LLM Service does exactly that: a credit-based module with multi-model chat and AI API in one place. Sign up with invite code QW4Z3F to get in — full disclosure: B.AI publishes no reward for the invited user. New accounts get registration Credits, and top-ups earn 50% bonus Credits (100% in BNB), up to US$100 per account; all of it expires 30 days after issue. Top-up options are generous: fiat (Stripe-supported cards, WeChat Pay, Alipay, UnionPay) or on-chain, and you log in with a Web3 wallet signature or Google-style centralized login. Stick to the official hosts listed in their docs (chat.b.ai or chat.bankofai.io) and don't wander into lookalike domains from ads. Credits pay for LLM usage — they're not cash you can withdraw, every Credit purchase is final and non-refundable, and you must be 16 or over. Before serious use, confirm the model list, API base URL, privacy terms and pricing on the live docs. It's a blockchain-adjacent ecosystem, so weigh the custody risk of wallet logins and on-chain payments yourself.

Pros
- Credit-based multi-model LLM chat and API access in one B.AI module.
- Flexible login (wallet or centralized) and both fiat and on-chain top-up paths per docs.
- Official docs list alternate access URLs if one entry point is unstable, and invite code QW4Z3F can be entered there.
- Useful if you already want B.AI’s LLM Service rather than chasing a cash bonus.
Watch out for
- B.AI publishes no invitee reward, bonus Credits expire 30 days after issue, and all Credit purchases are final and non-refundable.
- Credit balances are for LLM usage, not withdrawable cash.
- Wallet / on-chain top-ups add crypto custody and network-fee risk.
- Third-party multi-model routing — not an official OpenAI/Anthropic product; privacy and model claims follow live B.AI terms.
- Payment channels, prices and model list can change; always check the live Top up and model picker.
- Avoid phishing: only use official B.AI access URLs from docs.

TeamoRouter
Tired of opening accounts with every model vendor? TeamoRouter is a prepaid LLM router that speaks OpenAI, Anthropic and Gemini formats, built for Claude Code, Codex and other coding agents. The pitch: live per-model discounts marketed up to around 90% off list price. Full disclosure first: this invite has no fixed cash signup bonus — you buy prepaid credits (USD usage value) and spend them at discounted rates. Discounts are live prices that move with upstream costs, so this is not a permanent 90%-off guarantee. No subscription is required and purchased credits don't expire; promotional and referral credit can, and unused purchased credit is refundable minus fees. Base URL is https://api.teamorouter.cn/v1; for Claude Code, set ANTHROPIC_BASE_URL=https://api.teamorouter.cn (no /v1) plus ANTHROPIC_AUTH_TOKEN. Remember: TeamoRouter is an independent third-party router, not official OpenAI, Anthropic or Google — and it logs request and response content and stores it in Hong Kong (operator: Teamo HK Limited, Kowloon). Check the live pricing table (USD per 1M tokens) before any heavy spend. Invite code a3a4fa8a95 attaches automatically.
Requirement: Prepaid packs of $10, $20, $50 or $200, or any amount from $5 via Stripe; no subscription; purchased credits don't expire
Easy5-15 minutesPayout Live per-model discounts apply to prepaid credit usage as you spend; there is no fixed cash signup bonus

Grokified
Your IDE and coding agents are thirsty. Grokified is an OpenAI-compatible API built for IDEs and coding agents (Cursor, Claude Code, Codex and friends): sign up through the referral link and a $5 signup credit lands — usage credit, not cash — but it stays locked until you pay for the first time. Make that first payment $4.99 or more and another $5 drops in, so a $5 top-up leaves you with $15. Nothing runs before that first payment. The headline trick: 50% off all usage for the life of the account, no ceiling, no code, no claim step. Plans multiply your prepaid credits. Privacy check: requests and responses are kept for 30 days and never used for training. Grokified is an independent gateway run by DEEPORAX AI LTD, a UK company incorporated on 22 June 2026; its terms say it's not a reseller of any model vendor, and it's not official xAI. USD pricing; plans auto-renew but are marketed as cancel anytime — live billing terms have the final word.
Requirement: First payment of at least $4.99 (top-ups from $5, or Basic) unlocks the credit; nothing runs before it
Easy5-15 minutesPayout The $5 signup credit lands on account creation but stays locked until your first payment; a first payment of $4.99 or more adds $5 more (a $5 top-up gives a $15 balance)

AIJWS
Got BYOK tools waiting for a custom base URL? AIJWS is the OpenAI-compatible third-party LLM API gateway at api.aijws.com. Register through the affiliate link and code A8RXXLZYJ3EL attaches automatically. Saying it plainly: AIJWS publishes no sign-up bonus for invited users — it's prepaid / pay-as-you-go usage, and any starting balance shows in the console after sign-up. Also know this: AIJWS runs Sub2API, open-source software that resells pooled AI subscriptions through API keys, and its own README warns that using it may breach Anthropic's terms. AIJWS is not an official OpenAI or Anthropic product; model names, pricing and authenticity follow its live console and terms. Base URL is https://api.aijws.com/v1 (or whatever path the live docs show). Before heavy use, run one small paid test to confirm model IDs, streaming and billing; on privacy, assume prompts flow through AIJWS and upstream providers, so don't send anything sensitive. Registration and the dashboard may throw Cloudflare challenges — set your own spend caps.
Requirement: Fund the account via the AIJWS billing page before sustained use; the console shows the minimums
Easy5-15 minutesPayout Prepaid gateway usage after registration and top-up; AIJWS doesn't publish a sign-up bonus for invited users
